Did you see the sunrise Saturday morning?  It was one of those rare, surreal sunrises in which the sky appears to be on fire.  The fiery colors reflected brilliantly off of the frozen Tidal Basin.  It was a rather unique weather scene.

It’s also not every winter that large expanses of ice cover area waterholes like the Potomac while we have snow on the ground. A relatively mild Saturday afternoon provided a few-hour respite from four days below freezing, and a great opportunity to take in a mid-winter dusk.

To cover our unique weekend of Washington’s “fire and ice,” we divided our photographic efforts to shoot a sunrise at the Tidal Basin and to photograph the icy Potomac River at dusk.

In addition, we have included details on how to forecast the “perfect sunrise” as well as a brief look at why we’re getting an ice-covered Potomac.

Chasing the perfect sunrise

Approaching clipper storms often produce the most colorful sunrises because they are typically dry storm systems that occur in clear, clean winter air.  In addition, there is usually no fog, dense overcast, and overrunning precipitation in advance of clippers.

Thus, the rising sun’s light is unobstructed and can shine strongly underneath the cloud structure of the approaching storm. Timing is everything, however.  The storms need to approach at sunrise.  Here’s a Capital Weather Gang article describing how to predict a good sunrise using satellite imagery.

It doesn’t always end so good. Last weekend’s clipper chase was a  complete fail, as the storm dissipated crossing the Appalachian Mountains just before sunrise.  There are many weather-related spoilers that can ruin a colorful sunrise.  A few include: too many clouds, not enough clouds, hazy air, fog, and cloud banks just east of the horizon.

Predicting a colorful sunrise is never easy, not even a couple of hours before the sun is scheduled to rise above the horizon — the same can be said about sunsets.

The sunrise timeline shows the rapidly changing sky conditions that occurred from from dawn through sunrise, January 25, 2014.  The sky’s color and the mood of the scene changed within minutes.  As a reference for the timeline, sunrise in Washington, D.C. was at 7:20 am.  (Kevin Ambrose)

A wintry evening and lots of river ice

Nothing was quite going to beat the sunrise witnessed across the area that morning, but all the cold weather of recent has delivered increasingly formidable sheets of ice to area waterways, including the Potomac River around D.C. A sight to see.

While some ice isn’t unusual, the near total coverage as well as thickness is. We’ve had cold bouts throughout the winter, but January has turned into something special with two lows in the single digits at D.C., numbers not seen in one month since Feb. 1996 (2) or Jan 1994 (6).

The views remind one a little of photos from the 1970s, when people skated on the Potomac. This January is no 1977 (more than 10 degrees below normal compared to ~3 below normal so far in 2014). While some smaller ponds are perhaps now safe enough to maneuver on, it’s best to stay off ice unless you are very sure of what you are doing, and doing so on the river is always best assumed to be unwise.

Specific ice thickness aside, the Potomac sheet provided an excellent foreground to a very wintry late day. Occasional snow showers, steely gray skies, and the sounds of breaking ice on the river. Real winter in D.C.?
